Our research area ranges from digitization of audio and video signals through signal processing and transmission techniques to the reproduction of audio and video with audiovisual devices. The main focus is the system solution, so that the individual aspects of source coding, adapted channel coding and mobile transmission methods are coordinated. In the field of transmission methods, new broadband mobile radio systems and audio/video over IP are focused.
